WAGON-BRAKE.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed Septembei 21, 1905- i Serial No. 279,479.

To all whom it may concern:

Be it known that I, MARION W. ADKINs, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented new and useful Improvements in IVagon-Brakes, of which thefollowing is a specification.

My invention relates to improvements in wagon-brakes.

The object of my invention is to provide a device for supporting thebrake-beam of a wagon in a manner such that when the beam is moved awayfrom the wheels it will be held by gravity from contact with the wheels,the supporting device being provided with adjustable means for beingsecured to the hounds of the wagon, whereby the beam may be properlypositioned.

The novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawings, Figure 1 is a perspective view of abrake-beam and beam-supporting device of my invention. Fig. 2 is a topview of what is shown in Fig. 1, the hounds and part of the reach beingshown in dotted lines. Fig. 3 is a cross-section taken on the dottedline a b of Fig. 2, one of the hounds being shown in solid lines.

Similar characters of reference denote similar parts.

1 denotes an ordinary brakebeam .having the shoes 2.

3 denotes the brake-beam-supporting bar disposed parallel with and abovethe brake- 'beam and having at each end a loop 4., having a horizontalportion 5 disposed transversely at the end of the bar, the forward endof said horizontal portion terminating in a depression 6. The brake-beamis supported by two devices, such as eyebolts 7, said eyebolts beingslidable upon the horizontal portions 5 and into the depressions-6 whenthe beam is moved from the wheels to a certain position.I/Vhenpositioned in the depressions 6, the eyebolts will be retainedtherein by gravity, thus keeping the beam 1 from moving rearwardly to aposition in which the shoes 2 will have contact with the wheels. (Notshown.) By reason of the loops having the rearward horizontal portion 5,upon which the eyebolts slide when moving into the braking position, thebrake-shoes will, irrespective of wear upon them, always be broughtagainst the wheels at the same place I and angle, thus causing even wearupon the shoes.

The bar 3 is secured in any desired manner to the upper side of ahorizontal member 8, preferably a metal plate, which rests upon theupper sides of the bounds 9, upon which the member 8 is movable forwardand backward and laterally, thuspermitting the prop er positioning ofthe bar 3 and brake-beam 1 so that the shoes 2 may be in suitablepositions for engagement with the wheels of the wagon. The member 8 isprovided upon opposite sides of the bar 3 with longitudinal slots 10,arranged two at each side of the bar and two adjacent each end of themember 8.

.Two U-bolts for embracing the hounds 9 and denoted by 11 are insertedthrough the slots 10, one at each end of the member 8, the bolts beingsecured to the member 8 by nuts 12, mounted on the screw-threaded upperends of the bolts and resting upon the upper side of the member 8. Toadjust the beam 1 and bar 3, the nuts 12 are loosened, after which themember 8 may be moved forward or backward or endwise, the U-bolts beingmovable lengthwise of the hounds to accommodate the positioning of themember 8. When the member 8 is properly positioned, the nuts 12 aretightened upon the bolts 11 and against the member 8. The bar 3preferably has the loops 4 formed integrally thereon by forging, and themember 8, if desired, may be formed integral with the bar 3.

My invention may be modified in different ways without departing fromits spirit.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

The combination with the brake-beamsupporting bar bent downward atits ends, said bent ends being formed into two integral loops, each loophaving a transverse horizontal portion the forward end of whichterminates in a depression, of the brake-beam having two eyeboltsslidably mounted respectively on said horizontal portions and into saiddepressions, and means for adjustably securing the brake-beam-supporting bar to the hounds.

2. The combination with the brake-beamsupporting bar bent downward atits ends, said bent ends being formed into two integral loops, each loophaving a transverse horizonwith a depression, of the brake-beam, two
